Lelters Patent No. 93,099, dated July 27, 1869.

IMPRovED APPARATUS FQRMA'KING :summuml The Schedule referred to in these Letters Patent and making of the same.

To all whom it may concern:

Be it known that I, HERMAN LEKKER, of Pomeroy,

in the county of Meigs, and State-of Ohio, have in' ing had to the accompanying drawings, making a part refuse water left after the manufacture of salt from the saline products of certain earth-wells, or from seawater;

The invention consists in,making the still, in which the process is carried on, of tile, and all in one piece, so that there shall be no evaporation `of bromine, a thing impossible to prevent, if a still is used' in which there is any joint.

The invention further consists in placing the still directly over or in contact With ues leading from the main furnace, so that thereshall be but one fire beth to boil the mother-water and furnish the heat necessary for distillation.

In the drawings- Ais the furnace;

B, the pan in which the bitter water is boiled; and

G G, the pipes for conducting vthe liquor from the pan B to the stills E E.

'Ihe arrangement of these parts I do not claim as new.

The stills E E are made of tile, and all in one piece. This mode of manufacture is original with myself. It is a great improvement upon the old style of still made with joints, as, however tightly such a still may be put together, it is impossible to prevent evaporation of the volatile bromine, when in a gaseous state, and such evaporation is both a waste of valuable 'property and deleterious to the health of the workmen; all which is avoided by theuse of a still like mine, made without joints, in one piece, from which no gas Acan escape, save the very small quantity that finds its way through the necessary pipe-holes, which are to be found in all stills.

A further improvement in my apparatus is tl'v arrangement of the fines C, (l, and D, all three of which ai'ordready communication. betweenthe' furnace and the chimney. The two iues C O pass directly under the two stills E E, and thus supply the heat required for purposes of distillation from the same-fire that boils the mother-water in the pan B.

I do not know of any other mode of manufacture which does not require the use of two res, one for the evaporating-pan, and the other for the stills. But the heat of the main furnace is amply suiicient for both these purposes, and I thus effect a considerable saving. The branch flue D runs between the stills, and, by means of dampers, the heat maybe shut o' from. the stills when desired, and conducted straight to the chimney, without vat all diminishing the lire under the evaporating-pan.

Having thus described my invention,

What I claim as new, and desire to secure'by Letters Patent, is

1. The use of tile for the material of a bromine-still.

2. Making a bromine-still of tile, all in one piece, without joints. A

3. The arrangement of the stills E E, with the flues C C, D, by which the evaporating-pan and stills are heated-by one fire, or the products of combustion may be conducted past the stills without heating them, substantially as and for the purpose described.`

To the above specification of my improvement,-I have set my hand, this 10th day of July, 1869.

HERMAN LERNER.
